/ climbing the arete to left of elder crack at curbar edge

The arete to the left of elder crack at curbar edge has not been climbed.
Is it possible to climb it free? Has anyone tried any moves on a top rope?
Looks like the only thing that can hold a climber on the arete is friction.
Or are there some good pebbles somewhere?

He only misses out 1 move on the arete, because he has to place the six. Don't you reckon it would be a bit contrived to place the six, down climb a bit of elder, then head back up the arete? Or maybe you're thinking forget the six and go balls out?

In reply to jonny2vests:
It would be contrived going back down.
That move steve maclure makes shows what a creative thinker the guy is.
And it still takes a lotta bottle to do it.I know he claims he isn't into danger but I reckon his idea of danger and mine are two very different
things.What I want to know is has anyone actually hung onto the bottom of the arete and managed to move upwards -even one move!What grade do people
think it will be if/when it is done?
